SHUTTLE BINDER AND CHECK FOR LOOMS.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed April 4, 1914. Serial No. 829,448.

To all whom it may concern Be it known that I, JOHN G. CAYTEN, a citizen of the United States, residing. at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Shuttle Binders and Checks for Looms, of which the following is a specification.

This invention relates to shuttle binders and checks for looms.

The object of this invention is to allow a comparatively easy entrance of the shuttle into the shuttle-box by making the initial pressure of the binder very lig t and when the shuttle has gone more than half way into the box, by increasing the binding pressure so that when the shuttle has reached the end of its path the pressure of the check and binder on the shuttle is such as to prevent any rebound of the shuttle in the box, so that the shuttle is absolutely locked until the next stroke of the picker. The check and binder cooperate so that the outward movement of either increases the pressure of the other.

This invention allows me to dispense with the usual binder springs,(commonly leafsprings bolted to the lay-beam and pressing against the outer side of the binder)--which wear rapidly, and with the dagger-rod spring-(a coiled wire sprin surrounding the dagger-rod near the middle of the same and at its opposite ends connected to said rod and to the lay beam to hold the daggerrod fingers against the binders) which fre quently breaks; and thus effects a considerable saving. The dagger-rod spring has the disadvantage of tending to expand longitudinally and therebypushing the dagger-rod endwise in such a manner as to crowd one dagger-rod finger toward the hub of the corresponding binder and of drawmg the other dagger-rod finger nearer the free end of the other binder causing the fingers to press unequally the corresponding binders and sometimes one of these fingers 1s drawn off from the free end of its bmder causing breaking of the warp, the shuttle and other parts. The advantage of a loose box 1s in enabling the binder stud to remam 1n one position and the screws which hold the top and back of the shuttle-box to be fixed without the need of adjustment when changes of weather from day to day cause a swelllng or shrinking of the shuttle because the cheek can be adjusted much more easily by moving the check in toward thebox to cause the check to project farther into the box when the shuttle shrinks and in the opposite direction when said shuttle swells, or the same result may be attained by stretching or relaxing the check-spring.

In the accompanying drawing, Figure 1 is a plan of the left end portion of a lay-beam and. of its shuttle-box with my improvement applied thereto; Fig. 2, a rear elevation of the same; Fig. 3, a left end elevation of a part of the loom-frame, shuttlebox, shuttle,

binder, check, dagger-rod, dagger and frog,

and a section of the lay-beam on the line 3 3 in Fig. 1; Fig. 4:, a plan of the check detached; Fig. 5, a. side elevation of the arm of the check engaging a part of the checksprmg; Fig. 6, a rear elevation of the binder; Fig. 7, a plan of a slight 1nodification, showing the check pivoted on the binder instead of on a separate stand, showing also the check-spring, and a part of the check lever and shuttle; Fig. 8, a rear elevation of the pivoted end portions of the modified binder and check shown in Fig. 8.

A indicates the lay-beam, which serves also as the shuttle-race and bottom of the shuttle-box and is provided with the slot a, in which the picker-stick B swings to throw the shuttle C; D denotes the binder provided with a hub (Z which turns on a vertical binder stud (Z E represents the dagger-rod or protectonrod which turns in journals (one of which is shown as c, Fig. 3) secured to the underside of the lay-beam, and has a dagger c which is normally raised to clear the frog F by a shuttle in either box pressing the corresponding binder against a dagger-rod finger 6 but when a shuttle is in neither box the dagger is down in the position shown by dotted lines in Fig. 3 and in the forward movement of the lay will strike said frog and move the same to throw the shipper lever out of its holding notch and stop the loom, all the above named parts being of the usual construction and operation except as hereinafter described.

The binder D is provided with an opening (Z from front to back to admit the swell g of the check G which is pivoted at its outer end on a vertical stud 9 supported on a stand 9 bolted to the back of the lay-beam A and by means of the slot 9 adjustable to bring the swell to work freely in the opening (Z without striking the ends of said opening.

The stud g is provided with a shoulder g which rests on the top of the horizontal upper part 9 of the stand 9 and thereduced part'o'l said stud below said shoulder is passed down through a slot g in said stand and threaded to engage a nut g which, being loosened, allows said stud g to be adjusted toward and from the shuttle-box to cause a greater or less projection of the swell 9 into the boX'as the shuttle becomes worn or when a worn shuttle is replaced by a new or laterally thicker one. The inner end of the checkis provided with an armg which extends horizontally backwardand is trans versely concaved at 9 to fit a spiral spring H one end of which is a hook it whichengages one of a series-ofholes g in the check and the other end of which engages the short arm 7 of a horizontal check lever I which turns upon a vertical pivot stand 2' and'has another arm 71 which bears'against the back of the adjacent dagger-rod finger e and presses said finger against the corre sponding binder, said arm 2' being hollowed at 2' as shown in Fig. -1,-to receive said finger. By changing the hook it of the spring H from one'to another of the holes 9 nearer to or farther from the check-lever the tension of said spring H may be diminished or increased.

The check devices herein described will be applied to each end of the lay-beam and may be used equally well where the binder .is at the front of the shuttle boxas where it is in the position shown in the drawing.

lVhenthe shuttle enters the box it is'first pressed very slightly by the hinder, then strikes the check and crowds said check outward stretching the spring and crowding the dagger-rod finger with force against the binder and pressing the latter against the shuttle. The outward movement of either the binder or check increases the'tension of the spring. and causes the other of these parts to press with greater force upon the shuttle. By careful adjustment of the parts the shuttle may be stopped against the picker when the picker-stick is at the outer end of its slot, without inflicting a violent blow upon the picker and thereby incurring the risk of breaking said picker stick.

In the modification shown in Figs. 7 and 8 the check G is represented as pivoted at g between ears 6Z3 d integral with the binder D thus dispensing with the separate stand g shown in Figs. 1-3, the body of the check extending from the middle of its bearing sleeve 9 instead of from the top of the corresponding sleeve 9 in Fig. 2. The other parts shown in these Figs. 7 and 8 are shown in thefigures previously described and operate as above described.

I claim as my invention 1. The combination in a loom, of a binder having an opening, a pivoted check extending through said opening into the shuttlebox and into the path of the shuttle, the dagger-rod'having a finger, and connecting means between said check and said finger to press said finger against said binder.

2. The combination in a loom, of a binder having an opening, a pivoted check extending through said opening, a check-lever, a spring connecting said check and one arm of said check-lever, the dagger-rodhavinga finger, the other arm of said check-lever pressing said finger against said binder.

8. The combination inaa loorn, of a binder having an opening, a pivoted check extending through said opening, a check-lever, a spring connecting said check and one arm of said check-lever, the dagger-rod having a finger, the other arm of said check-lever pressing said finger against said binder, said check having an arm arrangedin contact with spring to increase the tension of said spring and the pressure of said fingeron said'binderas the check is forced out of the box by the incoming shuttle.

In witness whereof, I have aflixed my signature in presence of two witnesses.
